What is the Normal Range of Blood Oxygen Saturation for Children?

The normal range of blood oxygen saturation in children is 95% to 98% for arterial blood oxygen saturation and 65% to 85% for venous blood oxygen saturation. Close attention should be paid to changes in blood oxygen saturation. Blood oxygen saturation refers to the percentage of oxygenated hemoglobin bound to oxygen in the blood compared to the total hemoglobin capacity that can be bound. There is no significant difference between children and adults in terms of blood oxygen saturation. If the blood oxygen saturation in children is higher than the normal range, it generally has no clinical significance and is most likely caused by oxygen inhalation. If the blood oxygen saturation in children is lower than the normal range, it may be related to lung diseases such as pneumonia, tuberculosis, asthma, etc. It is necessary to promptly go to the hospital for physical examination, CT scan, and blood routine examination for diagnosis to identify the cause of the lesion. If the body lesion can be diagnosed, active treatment should be followed according to the doctor's advice to avoid aggravating the degree of body damage. During the treatment stage, it is necessary to closely monitor changes in blood oxygen saturation levels. If there is insufficient oxygen intake in the body, timely medical attention and oxygen inhalation treatment should be sought to increase blood oxygen saturation. In daily life, children can participate in outdoor activities appropriately to breathe fresh air. However, they should avoid strenuous activities, especially anaerobic exercises. If abnormal physical conditions recur, prompt medical attention is required.
